The 35-year-old model and actress matched her outfit with tight black Nike leggings, bright sneakers and showed off her tanned arms.
At one point, the Piranha 3D actress stuck her tongue out and gritted her teeth as she performed a difficult leg exercise with her hands in a praying position and an exercise rope between her legs.
